2. Performance Advantages

Large F1.0 aperture: This infrared lens features ultra-large aperture, greatly boosting infrared photon receiving efficiency. The thermal imaging lens produces clearer thermal images in low-thermal-radiation environments compared with smaller aperture counterparts.

Excellent optical uniformity: Relative illumination higher than 97% effectively avoids dark corners at image edges; distortion under 2% ensures geometric accuracy of thermal footage, critical for measurement-based thermal systems.

Robust environmental adaptability: IP67 front lens protection allows dustproof and temporary waterproof outdoor usage. Wide temperature range eliminates defocus drift under severe temperature changes.

High transmittance AR coating: The coating on this 25mm F1.0 lens reduces surface reflection, raising infrared energy utilization rate and improving signal-to-noise ratio for thermal cameras.

Mature standardized interface: M22×0.5 mount enables flexible interchange and quick mass assembly for equipment manufacturers partnering with ShangHai SLIK Optical Technology CO., LTD.

3.Application Fields

Outdoor perimeter security surveillance: The thermal camera lens works for border defense, factory and campus perimeter thermal monitoring, detecting intruders day and night without visible light.

Industrial predictive maintenance: This LWIR optics is installed on thermal inspection cameras to check overheating faults of power equipment, mechanical bearings, electrical cabinets.

Traffic and transportation monitoring: Used in road traffic thermal sensing, vehicle heat detection, and abnormal temperature alarm systems.

Unmanned system payloads: The compact 25mm F1.0 infrared lens fits ground robots and small unmanned aerial vehicles for search & rescue missions in fog, night or smoke conditions.

Fire prevention and early warning: Deployed in forest fire monitoring, warehouse temperature early warning, capturing abnormal heat sources at medium distances.
